Each application for an alternative shall be filed with the state fire marshal and shall be accompanied by such evidence, letters, statements, results of tests, or other supporting information as may be required to justify the request. The state fire marshal shall keep a record of actions of such applications and a signed copy of the state fire marshal's decision shall be provided for the applicant. The state fire marshal may grant or deny any properly filed application; but if the state fire marshal does not deny an application within twenty days of its filing, the alternative shall be deemed granted.
